Separate ISYs on Different ISPs

[smokegrub]

I have ISYs at two separate locations, each using a different ISP. The primary location is in the ISY Portal and is successfully working with the app to control 5 Echo’s. The secondary location is also in the Portal, and I can successfully access the secondary ISY and control devices at that location. I have not yet added any Echo’s at that location, but will do so in a couple months when I am on scene. I have read the wiki, but I am at a loss as to how to add Echo’s at that site and have them only control devices at that location. My guess is that I must set up a separate Amazon account for that location. Is that correct? Will that require a second app??? Some help/guidance will be much appreciated.

I have five accounts, actually a main account and four sub-accounts. Echo devices assigned to a specific account control only devices. scenes and/or programs added to that specific account. I can and do have a few devices, scenes and/or programs added to more than one account. In those cases, a command to either Echo device will control that particular device, scene or program.

Thanks, Stu. As always, most helpful, but I am still uncertain of next steps. For the purpose of simplification of my request, I offer the following:

I have two ISYs located at different homes which, for the purpose of illustration I will refer to as A and B. I have an ISY portal set up for each home. Portal A has 5 Echo’s and is setup complete with spokens and works fine. Portal B will soon be set up up and receiving one Echo. I have read and read about setting up this second portal, and this is what I think I need to do:
1. Create a new Amazon account (non prime).
2. Include the Echo at B in the portal for B.
3. Set up spokens in Portal B.

Will I end up with two apps on my iPhone using this approach? I would prefer to avoid that.

It appears to me that using this approach spokens at B should be completely segregated from those at A. Am I correct?

Any help will be appreciated.
